Answer: The required system of equations representing the given situation is
Step-by-step explanation: Given that Sam needs to make a long-distance call from a pay phone.
We are to write a system to represent the situation.
Let x represent the number of minutes Sam talked on the phone and y represents the total amount that he paid for the call.
According to the given information,
with prepaid phone card, Sam will be charged $1.00 to connect and $0.50 per minute.
So, the equation representing this situation is
Also, if Sam places a collect call with the operator he will be charged $3.00 to connect and $0.25 per minute.
So, the equation representing this situation is
Thus, the required system of equations representing the given situation is
Answer: 0.139
Step-by-step explanation:
From the given table, the total number of females = 252. The number of females that owned cats = 35. Therefore , the relative frequency of women that owned cats is given by -
Number of females that own cats/ Number of females
= 35/252 = 0.138888888889 = 0.139
Therefore, the relative frequency of women that owned cats is 0.139.
Sabemos que
el costo del televisor es -------> 130000
si se pago (1/4) al contado-------> (1/4)*130000=32500
quedo pendiente por pagar------> 130000-32500=97500
la cantidad pendiente por pagar se divide en 6 giros
97500/6=16250
La respuesta es
el valor de cada giro sera de 16250
Answer:
All real numbers
Step-by-step explanation:
4(x+1) = 4x+4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4
This is always true so there are infinite solutions
Answer:
y = -½x + 4
Step-by-step explanation:
1 = -½[6] + b
-3
4 = b
2y + x = 4 →2y = -x + 4 >> y = -½x + 2 [parallel to the above equation]
Parallel lines have SIMILAR <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>].
I am joyous to assist you anytime.
**I have a video that explains how to find the y-intercept, Perpendicular Equations, and Parallel Equations. I encourage you to watch the video to gain alot more knowledge from it, so you can better understand the concept. It is the second longest.
